What you'll learn in this Python course

Functional programming is back in vogue. There's a reason front-end frameworks like React and Vue are moving toward functional programming, and after this course you'll more than understand its benefits. We'll dive in-depth into all of the foundational concepts of functional programming in a familiar language.

Chapter List

1
Functional Programming
Learn about the difference between OOP and functional styles, and what the real difference is: imperative vs. declarative
2
First-Class Functions
First-class and higher-order functions are foundational to everything we do in the functional paradigm.
3
Pure Functions
My favorite part of functional programming is the focus on pure functions that are easy to test and reason about
4
Recursion
While not unique to functional programming, recursion is a powerful tool that is used often when trying to avoid imperative code
5
Function Transformations
Learn how to transform functions into other functions to write more abstract and generalized code
6
Closures
Learn about encapsulating state within functions and how to use closures to write more expressive code
7
Currying
Learn to transform a function with multiple parameters into a series of functions with one parameter, and why you might want to do that
8
Decorators
Learn about Python's decorators and how they're essentially syntactic sugar for higher-order functions
9
Sum Types
Learn about sum types, a powerful way to represent data that is used in many functional languages

"Great hands-on course that clearly breaks down functional concepts like immutability, pure functions, and recursion with practical Python challenges!"

In my opinion, this course is exceptionally so structured and provides a deep, thorough understanding of functional programming concepts in Python ranging from higher to order functions and decorators to expression based data handling. The material truly sharpens my programming logic, teaching me how to write clean, efficient, and robust code.

Actually a great course, despite an absolute enormous spike in difficulty in the last few lessons. Gruesome, brutal finish, but worth it
